Voice AI Calendar App

0sec is a voice AI calendar app that schedules events and manages time using voice commands.

In plain English

potemin made a calendar app you control by speaking. You talk, and it schedules events and helps manage your time, which suits anyone who finds tapping through a calendar to be a chore. People pay a subscription because a calendar only helps when adding a plan is quick. The AI does most of the listening and the scheduling, and payment collection is handled too. potemin still checks quality, helps users, and shares the app through the phone app store and short videos.
